In this study, we build on the previous findings of increased diabetes prevalence among American Indian/Alaska Native (AI/AN) young adults, by studying the rate at which annual prevalence estimates of diagnosed diabetes increased from 1994 to 2007.
For this study, BRFSS data for 1994-2007 from the 50 states, District of Columbia, Puerto Rico, Guam, and the Virgin Islands were analyzed.
Only non-institutionalized adults aged 18 years and older were eligible to participate in the Behavioral Risk Factor Surveillance System survey.
To examine the existence and strength of a trend, we analyzed plots and Spearman's rank correlation coefficients of annual prevalence estimates for each group of young adults. Mantel-Haenszel tests were employed to study the relationship of diagnosed diabetes prevalence and race (AI/ AN, non-Hispanic White), while controlling for the time periods 1994-2000 and 2001-2007. To quantify increases in the disparity of diagnosed diabetes prevalence and race (AI/ AN, non-Hispanic White), odds risk ratio estimates were employed to approximate corresponding prevalence ratio estimates for the time periods 1994-2000 and 2001-2007.
Employing Spearman's test for trend resulted in observing, during 1994-2007, statistically significant increasing trends in the annual prevalence estimates of diagnosed diabetes among AI/AN and non-Hispanic White young adults. AI/AN young adults, on average, were 1.7 (95% CI; [1.12, 2.63]) times more likely than non-Hispanic White young adults to be diagnosed with diabetes during 1994-2000 and 2.5 (95% CI; [1.93, 3.32]) times more likely during 2001-2007.
The findings in this study suggests that the disparity in the estimated prevalence of diagnosed diabetes between AI/AN and NHW young adults widened steadily from 2001 to 2007.
在本研究中，我们基于之前关于美国印第安人/阿拉斯加原住民（AI/AN）年轻成年人中糖尿病患病率上升的研究结果，研究1994年至2007年确诊糖尿病的年度患病率估计值的增长速度。
本研究分析了来自50个州、哥伦比亚特区、波多黎各、关岛和美属维尔京群岛的1994 - 2007年的行为危险因素监测系统（BRFSS）数据。
只有年龄在18岁及以上的非机构化成年人有资格参与行为危险因素监测系统调查。
为了检验趋势的存在和强度，我们分析了每组年轻成年人年度患病率估计值的图表和斯皮尔曼等级相关系数。采用曼特尔 - 亨塞尔检验来研究确诊糖尿病患病率与种族（AI/AN、非西班牙裔白人）之间的关系，同时控制1994 - 2000年和2001 - 2007年这两个时间段。为了量化确诊糖尿病患病率与种族（AI/AN、非西班牙裔白人）之间差异的增加情况，采用比值风险比估计值来近似1994 - 2000年和2001 - 2007年相应的患病率比估计值。
采用斯皮尔曼趋势检验发现在1994 - 2007年期间，AI/AN和非西班牙裔白人年轻成年人中确诊糖尿病的年度患病率估计值存在统计学上显著的上升趋势。在1994 - 2000年期间，AI/AN年轻成年人被诊断患有糖尿病的可能性平均是非西班牙裔白人年轻成年人的1.7倍（95%置信区间：[1.12, 2.63]），在2001 - 2007年期间是2.5倍（95%置信区间：[1.93, 3.32]）。
本研究结果表明，2001年至2007年期间，AI/AN和非西班牙裔白人年轻成年人之间确诊糖尿病估计患病率的差距稳步扩大。
